[DIRSERVER-2315] Having a schema with an object class that doesn't have any superior classes causes crash on replication

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 2.0.0.AM26
• Component/s: replication, schema
• Assignee: Unassigned
• Reporter: Kaamil Jasani
• Created: 10/Jun/20 12:45
• Updated: 12/Jun/20 11:46

Description

Either that is a bug in that a superior class is not needed but this exception still occurs, or perhaps if that is required then it would make more sense to fail when the LDIF is applied?
